启动电阻starting resistance，通常一端接（整流后）电源的正极，另一端接开关管的基极。 启动电阻右图中，1M的就是启动电阻。
这种负载对开关电源来说要比电阻负载容易启动。
This load is easier for power supply to start up than resistor load.
这种调速系统采用计算机控制，可无触点地调节转子的电阻来实现转子绕线式电动机软启动及调速。
By means of computer control, the speed control system can control the resistance of the motor without any contact, so to realize soft starting and speed control over the wound rotor motor.
同时指出传统的串电阻启动方式，由于自身的特点，在水电站卷扬式起重设备上仍然有广泛的应用空间。
There is much room for the traditional series-resistance start mode to exist, due to its characteristics, in windlass crane for hydroelectric power stations.
